STREET-SPRINKLING, IRRIGATING, AND FIRE-EXTINGUISHING SYSTEM.

sPn'cIFIcArIoN forming part of Letters Patent no. 605,611, dated June 14,1898. Application filed August 10, 1897. $erial No. 647,675. (No model.)

tions and combinations of parts hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 shows my inventionas applied to sidewalks.

Fig. 2 is a vertical section through the. same. Fig. 3shows it applied to houses. Fig. 4shows my device in connection with a tilting board.

A represents the curb at the side of the street, and B is a pipe of any suitable or desired material and size laid along the side of the curb, as shown, and havingone or more rows of holes made in it at suitable distances apart, so that jets of water may issue therefrom when water is supplied to the pipe under pressure. These pipes may be of any dimensions desired, and theholes should be finished with counterboredmetal bushings, as shown at Fig. 2, so as to impart a nozzle shape to them, and in order to equalize the jets of water thrown from them they should be graduated in diminishing diameter as their distance from the supply stand-pipe or hydrant increases.

A hydrant b may be placed at or'near the center of the street-block, supplied with a double stop-cock, and connected with the main water-pipe in the usual way. To each side of this hydrant my perforated pipes are .suitably coupled above the stop-cock in the hydrant, so that the water may be turned into the pipe on either or both sides of the hydrant, as may be desired. T

D are polygonal collars fixed on the pipe B at suitable. intervals, so as to enable it to be turned about its axis by the application of a crank shaft or lever. By the application of this crank shaft or lever the pipe maybe turned so as to present the row or rows of holes at different angles and thus direct the water over different portions of the surface to be sprinkled.

' When applied to lawns, the pipes can be laid along one or more of the edges of the lawn, according to its size, and by-rotatin g the pipes the angle of discharge of the Water may be altered so as to sprinkle the whole of the,

lawn. WVhen the lawn is very large, intermediate pipes may be used.

In order to lay the dust in the street, it is only necessary to turn the pipe outward, so that the water will be thrown onto the street, and I have found by experiment that a oneinch pipe, having holes bored at a short distance apart and having diameters gradually diminishing from the hydrant to the ends of the pipe, will easily carry water from one hundredandtwenty to one hundred and thirty feet in each direction from the stand-pipe or hydrant and with sufficient force to sprinkle the full width of an ordinary street.

Fig. 3 shows the application of my system to the inside'of a house for the purpose of extinguishing fire. The perforated pipes 13 may be laid wherever desired, preferably along the cornice, so as to be as much-out of sight as possible, or they may take theplace of the ordinary molding used for hanging pictures on, or they may be applied to the center piece on the ceiling. Whenthus applied to the interior of the house, the means of rotating them may bedispensed with, but aplurality of rows of holes may be used, so as to spread the water over the entire area of the room. By the use of suitable stop-cocks the application of the water may be confined to one or more of the rooms,as may be necessary, according to the location of the fire, which may thus be checked in its incipiency and a conflagration averted as well asdamage by flood in parts of the house. where the fire is not burning.

My system can also be effectively applied to the roofs of houses and large buildings, in which case I may turn the pipe, as before described, or use tilting boards F, as shown in Fig. 4. In this device the perforated pipe B is furnished with collars G at suitable intervals, which are secured to brackets I, fastened on the apex of the roof. The board F is fixed to suitable brackets F, journaled, as shown at J. Cords K of suitable material are attached to the ends of one or moreof these boards or to fixtures so attached to the pipe that they may be tilted, as desired, the cords communicating with either the interior or exterior of the building, as desired. By thus tilting the pipe or the board F from side to side the discharge from the perforations in the pipe may be delivered upon either slope of the roof, so as to flood it in case'of fire.

By the use of the supplemental nozzles of a non-corrosive metal and counterboring or tapering them from the inside the jet-holes are prevented from changing in size or clogging by rust and the jets are made smooth and even in discharge. 5

Having thus described my invention, what} I claim as new, and desire to secure by Letters Patent, is I 1. In a system of water-supply, a pipe hav-i ing one or more rows ofholes of decreasing? diameters, said holes provided with counter-i bored bushings, and polygonal collars on the pipes adapted to receive a tool or device whereby they may be rotated.

2. In a system of water-supply for extinguishing fires, a perforated pipe connected with a source of supply and journaled 011 the apex of the roof of a building, and means whereby the discharge from the pipe maybe directed to either slope of the roof.

3. A sprinkling device consisting of a pipe section or sections, having a line of perforations along one side, brackets by which said pipe is supported along the ridge of a house, a direction-board supported and turnable beneath the pipe with attachments to tilt the board and direct the discharge-jets to either side of the ridge.

In witness whereof I have hereunto set my hand.

ALEXANDER Moonoon.
